UNITED STATES CHRISTIAN J. BERGLANN, OF SEATTLE, WASHINGTON.

STOVE.

Specification of Letters Patent.

Patented Mar. 15, 1921.

Application filed April 19, 1920. Serial No. 375,166.

To all whom it may concern:

Be it known that I, CHRISTIAN J. BERG- LANN, a citizen of the UnitedStates, residing at Seattle, in the county of King and State ofWashington, have invented a certain new and useful Improvement inStoves, of which the following is a specification.

My invention relates to improvements in stoves that are adapted for useon ship board or in places where they are subjected to a tilting motionand the object of my invention is to provide a stove that is su.p portedby a universal joint within a frame in such manner that the top of thestove will always remain in, a horizontal position regardless of theangle at which the frame is moved.

A further object is to provide a novel frame structure and a novelarrangement of a ball and socket joint that is particularly adapted forsupporting an oil stove.

A still further object is to provide simple and efficient means forgrasping and holding a cooking 'utensil that may be placed upon thestove. I

A still further object is to provide novel means for preventing any dirtfrom lodging within the ball and socket joint of the stove. A stillfurther object is to provide a novel means for preventing the flame ofthe stove from being extinguished when the stove is used in an openboat.

With the above and other objects in view which will appear as thedescription proceeds, my invention resides in the novel con; struction,adaptation and combination of parts, as will be more clearly hereinafterdescribed and claimed.

I accomplish these objects by devices illustrated in the accompanyingdrawings, wherein Figure 1 is a view in side elevation of a stoveconstructed in accordance with my invention.

Fig. 2 is a view in vertical section of the same substantially on abroken line 2, 2 of Fig. 1.

Fig. 15 is a detail in perspective showing a fragment of a plate used inthe electrical stove.

Fig. 16 is a sectional view on broken line 16, 16 of Fig. 13 showingparts in plan.

Like reference numerals designate like parts throughout the severalviews.

Referring to Figs. 1 to 8 inclusive the numeral 1 designates a pan thatalso serves as a stove base andis provided on one side with an integrallug 2 into which the bottom end of an upright tubular support 3 istightly screwed. The upright support 3 is bent at right angles to form ahorizontal arm 4 that terminates in an upturned end 5 which ispreferably located substantially above the center of the pan 1.

The upturned end 5 is rigidly secured to a relatively large sphere orball 6 that fits within a socket in a two part yoke or mounting 7, smallbearing balls 8 being provided 1gviltlhin the socket and adapted to rollon the Suspended from the yoke 7 by two pipes 9 and 10 is a combinedfuel bowl and weight 11 that always tends to hang in a vertical positionregardless of the angle into which the pan 1 and upright support isturned.

The fuel bowl 11 has receptacle 12 for fuel and the pipes 9 and 10 arepreferably screwed through the top wall of the receptacle 12 and areconnected with smaller pipes 13 and 14 that project downwardly into thereceptacle and terminate near the bottom thereof so that fuel may beforced upwardly therethrough.

The fuel receptacle 12 is provided with aninlet opening 15 through whichfuel may be 7 adapted to be engaged beneath a cleat 23 on the side ofthe bowlv to hold the piston stem 20 in its innermost position when thepump is not in use.

19 is a safety valve that serves to relieve excess pressure of airwithin the oil reservoir 12. p I

The upper ends of the pipes-9 and. 10 communicate with a passageway orchamber 24 in the upper portion of the yoke 7 which passageway in turncommunicates with an oil burner 25 that may be of any desired well knownform.

Supported above the yoke 7 bythree equldistantly spaced brackets 26 is anormally horizontal plate 27 having a centrally arranged opening 28 andprovided with radial ribs 29 on which a cooking utensil 30 may rest. Thetop plane of the plate 27 is far enough above the top end of the burner25 so that the best results from the flame of such burner will beobtained. The top side of the plate27 is preferably slightly convex asshown in Fig. 2 so that liquids that may be spilled onto such plate willquickly drain off and be caught by the pan 1.

The ribs 29 support the cooking utensils far enough above the surface ofthe plane 27 so that flame from the burner may pass outwardlytherebetween and come in contact with practically the entire bottom ofthe cooking utensils.

The burner 25 is disposed within a housing 31 that is secured to theplate 27. The bottom of the housing 31 is provided with a plurality ofperforations 32 and one side of such housing is provided with an opening33 that is arranged to be opened and closed by a door 34 that is'slidable in guides 35.

The housing of the burner 25 and the provision of the door '34 makes itpossible to use this stove in the open in windy weather without dangerof having the fire extinguished by the wind. When the stove is used inthe wind the door 34 may be partially or entirely closed. At all othertimes the opening of the door 34 may be regulated to secure the draftthat is best for the flame of the burner.

As a means for retaining or holding a cooking utensil on the top of theplate 27 I provide-two arcuate arms 36 and 37 that are each free at oneend and are rigidly connected at the opposite end with pivots 38'relation to the arm 37 and is provided on its end with a downturnedportion 44 that projects through a slot 45 in the lever arm42.

l The lever arm 42 is fulcrumed on a fixed pivot 46 on the plate 27 andis provided with a pawl '47 thatis arranged to engage with teeth 48 onthe edge of the plate 27 to lock the lever 42 in a fixed position. 7

When the lever arm 42 is moved in a contra-clockwise direction from theposition shown in Fig. 3, the arms 36 and 37 will be moved away fromeach other so that a cooking utensil may be placed on the plate 27between such .arms. When the arms 36 and 37 are spread apart and thelever 42 is moved in a clockwise direction as viewed in Fig. 3, sucharms will be moved toward each other and may be caused'to engage withand hold a cooking utensil.-

From the above description it will be seen that the entire stove withthe exception of the base or panl, the supporting standard composed ofthe parts 3, 4 and 5, and the ball 6, is free to oscillate on theuniversal joint formed by the socket in yoke 7 and bearing balls 8 whichroll on the large ball 6 and that the relatively heavy bowl 11 willalways hold the stove in a vertical position with the plate 27horizontal regardless of the angular position into which the frame isturned.

The yoke 7 forms a cap or cover for the universal joint and serves toprevent grease and liquids that may escape from the cooking utensilsfrom gaining access to the bearing.

In Figs. 9 to 12 inclusive I have shown a slightly modified form of theinvention comprising a pan shaped base 50 thatis centrally provided witha lug 51 into which is screwed a rigid upright supportingpost 52.

Secured to the top end of the. post 52 is a relatively large ball orsphere 53 that fits within la-suitab'le socket= formedin a two partyoke. 54,:ibearing balls 55 being provided within the T socket. andadapted to roll on the large ball153 to thereby form a universal-joint.

Suspended from the yoke "54byimeans of threetubular-supports 56,57 and58 is a combined fuel receptacle and weight 59 that is preferably ofcylindrical shape and of relatively large diameter as shown in thedrawings, and that has a relatively large circular opening 60 in itscentral portion so that the post 52 may swing into various angularpositions without interfering with the fuel receptacle 59.

The fuel receptacle 59 is provided with a pump 61, a fuel inlet opening62, and a safety valve 63 that are all substantially identical with thesimilar articles described in connection with the bowl 11.

One of the pipes by which the fuel receptacle 59 is suspended, as thepipe 56, serves as a fuel conduit and is connected with a passageway 64in the yoke 54, which passageway 64 communicates with a burner 65 thatis identical with the burner 25 hereinbefore described.

The plate for supporting the cooking utensils, the means for supportingthe said plate above yoke 54, and the means for holding the cookingutensils in place on said plate are identical with the correspondingdevices described in connection with Figs. 1 to 9 inclusive.

The operation of this stove is substantially the same asthe operation ofthe stove shown in Figs. 1 to 9, the fuel receptacle 59 serving as aweight to always maintain the stove in a vertical position regardlessofthe angle into which the base 50 and upright support 52 are tilted, theamount of relative tilting movement between the stove proper and thesupporting mechanism being necessarily limited by the size-of theopening 60 within the bowl 59.

In Figs. 13 to 16 inclusive, I have shown my stove, which may be eitherthe type of stove shown in Figs. 1 to 8 or in the type shown from Figs.9 to 11, as provided with an electrical heating element that is disposedwithin a housing 66 which is secured toa plate 67 that is adapted to fitover the central opening 28 in the plate 27 upon which the cookingutensils are placed, the plate 67 being provided on its periphery withintegral channel shaped guides 68 that are adapted to fit over the ribs29 on the top of the plate 27 and the ribs 29 preferably being notchedas at 70 so that the plate 67 will be flush with thetop surface of suchribs 29.

If desired either of the types of stove hereinbefore described may beprovided with suitable means for locking them to prevent the operationof the universal joint,

which means may be employed when the stoves arein use in places wherethey are not subject to a rocking motion, or, if d'esired,-,means may beprovided for locking the-universal joint in such a manner as to preventuniversal movement of, the stove about such joint but still to permitswinging motion of the stove in a single plane.

From the foregoing description taken in connection with the accompanyingdrawings the advantages of the construction and of the method ofoperation of my shi stove will be readily apparent to those skllled inthe art to which the invention pertains, but while I have described theprinciple of operation of the invention, together with the device whichI now consider to be the best embodiment thereof, it will be understoodthat the structure shown is merely illustrative and that such changesmay be made as are within the scope of the following claims.

What I claim is:

1. A stove of the class described comprising a base, a rigid supportprojecting upwardly from said base, a ball secured to the upper end ofsaid support, a yoke arranged to fit over said ball and to oscillatethereon said yoke having a fuel passageway therein, pipes connected withsaid yoke and communicating with said fuel passageway, a combined weightand fuel reservoir secured to the bottom ends of said pipes andcommunicating therewith, an oil burner secured to said yoke andcommunicating with the fuel passageway therein, and a plate supported inoperative relation with respect to said oil burner.

2. A stove of the class described comprising a base, a rigid supportprojecting upwardly from said base, a relatively large ball secured tothe upper end of said support, a two part yoke having a fuel passagewaytherein and having asocket adapted to fit over the upper side of saidlarge ball, ball bearings disposed within said socket and arranged toroll on said large ball, downwardly projecting pipes secured to saidyoke and communicating with the fuel passageway therein, a combinedweight and fuel reservoir secured to the lower ends of said pipes, thesaid pipes communicating with the interior of said fuel reservoir, anoil burner connected with said yoke and communicating with the fuelpassageway therein, and a plate supported from said yoke in operativerelation with respect to said oil burner.

3. In a stove of the class described, a burner, a plate supported inoperative relation with respect to said burner for receiving cookingutensils, two curved arms each pivoted at one end to said plate forengaging with the sides of a cooking utensil to hold the same, a handlever fulcrumed on the bottom side of said plate, a catch memher-on saidhand lever, teeth on the edge of said plate and arranged to be engagedby said catch member, divergent slots in the 1 inner end of said handlever, and two aotu ating arms, each rigidly connected at one end withthe pivot of one of said eooking utensil engaging: arms and provided atthe other end with a downturned portion that is operatively disposed inone of the slotsin 10 the inner'end of said lever arm.
